Hello MaxS, thanks for contacting us through the Intel Communities.
This seems to be a cable issue, since the VGA monitor is working OK. It will be helpful to test the 29” TV using another HDMI cable. You could also try using VGA or DVI connexion if it has any of those video ports.
I would also recommend you to try our graphics driver version. You would be able to download it at the following link
MaxS, this seems to be an issue related to the video controller of the processor.
I recommend you contacting our customer support department for additional information on replacing your product if it is still under warranty.
You guys removed a very critical option from your control panel. Your driver overscans automatically once it detects a TV . There is no such thing as "TV" these days. You simply feed the PDP or LCD/OLED with native HDMI signal and still have overscan option enable/disable for people who otherwise need it.
I will check if there is a way to switch to other GPU (AMD/ATI) on this portable computer just because its driver still have option to disable overscan so we can see start menu. I am an Intel customer for years (since Pentium 75) and I have never seen Intel treat their advanced users like some sort of morons who will be confused by technical options. You can simply HIDE the option under 'advanced' menu so all would be happy.
This time I couldn't watch a movie or use my i5 Computer. It could be a very critical business presentation and I could lose the information on screen, no we can't tell people to throw away their Barco $50K projectors just because some guy there wanted to behave like Microsoft and removed technical options from integrated graphics. Mainly business guys/women choose Intel GMA since they care about 2D and simple (non game) 3D. Your guys remove a very critical option without asking anyone and inviting a very nasty surprise to your customers.
Actually this is exactly Apple/OSX behaviour, overscanning automatically and don't let user choose without doing crazy dangerous hacks. Every serious Apple user lived this one way or another. This is PC/Windows. People choose this configuration for flexibility and having such options. Whoever removes perfectly working things out there may go back to Apple.
